Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lamp for a vehicle, and more particularly to a lamp for a vehicle mounted on a vehicle and configured to irradiate light in at least one direction.

A vehicle is a device that moves a user in a desired direction by a boarding user. Typically, automobiles are examples.

On the other hand, for the convenience of the user who uses the vehicle, various sensors and electronic devices are included in the vehicle. Especially, for the convenience of users, researches on ADAS (Advanced Driver Assistance System) have been actively carried out. Furthermore, development of an autonomous vehicle is being actively carried out.

Such a vehicle is equipped with various kinds of lamps which irradiate light to easily confirm an object located in the vicinity of the vehicle, or output a signal related to the vehicle to a passenger of another vehicle or another vehicle, or a pedestrian.

For example, a head lamp attached to the front of the vehicle to illuminate the front, a fog lamp disposed around the headlamp to inform the driver or a pedestrian of another vehicle of the position of the vehicle, A turn signal lamp for outputting signals such as directions. A break lamp for guiding the braking of the vehicle, a back-up lamp for turning on the vehicle when backward, a tail lamp for recognizing the rear of the vehicle to the driver of the following vehicle, As shown in FIG. These vehicle lamps are regulated by the laws and regulations on the installation standards and specifications so that each function can be fully demonstrated.

A rear lamp of a vehicle lamp is disposed at the rear of the vehicle based on the direction of the driver's seat, and plays a very important role in preventing rearward collision. At least one of the above-described turn signal lamp, braking lamp, and reverse lamp may be included in the rear lamp.

Typical rear lamps include a lens that forms an external shape and transmits light, a light emitting portion that emits light, and a controller that controls ON / OFF of the light emitting portion. The rear lamp uses a reflector having an aspherical surface or a light guide pattern to form a fixed light distribution pattern.

The reflector or the light guide makes it possible for the person looking at the lamp to intuit the three-dimensional structure of the lamp, but it was difficult to make a three-dimensional light distribution pattern because of the limit of the light source itself.

Therefore, studies have been made to implement a three-dimensional light distribution pattern by changing the light source itself. For example, research has been conducted to realize a lamp using a surface light source. However, it is difficult to secure the amount of light specified by the law due to the characteristics of the surface light source, and research on the structure of a vehicle lamp capable of inviting an integrated aesthetic feeling and a high-level sensibility has not been studied yet.

In addition, because the lamp is a device that turns on the lights to illuminate dark areas or send signals, vehicle designers can use lamps to change the cold image of a vehicle-produced machine to a warmer image. For example, when a lamp that is turned off is turned on, a visual effect such as a moving vehicle may occur.

However, a general lamp has a problem in that it can not produce various stereoscopic effects because its shape is fixed.

In recent years, there is a growing demand for lamps capable of creating a visual beauty that distinguishes itself from other vehicles while maintaining its safety function.

An embodiment of the present invention is directed to providing a vehicle lamp and a vehicle including the same, for solving the above problems.

8A and 8B are front views of a vehicle lamp according to an embodiment of the present invention. Fig. 8A shows a vehicle lamp in an off state, and Fig. 8B shows a vehicle lamp in an on state.

The vehicle lamp 800 according to an embodiment of the present invention includes a frame fixed to the vehicle body and a plurality of surface light sources installed in the frame.

A wiring line for supplying power to the surface light source is connected to the frame, and the frame can be fastened directly to the vehicle body or fixed via a bracket. A transparent lens may be provided to further diffuse and brighten the light emitted by the planar light source.

The planar light source is a concept distinguished from a point light source and means a planar light source having a predetermined size. The surface light source includes a plurality of point light sources for diffusing light at the same time. The user recognizes not only the point light sources but also a predetermined region in which the point light sources are distributed as one light source.

The planar light source has a surface adapted to emit light, and is flexible to be deformable by an external force. The deformation may be at least one of warping, bending, folding, twisting, and curling of the surface light source. The deformable surface light source may be referred to as a " flexible surface light source ". A flexible planar light source refers to a sturdy planar light source that is lightweight and does not break easily, such as paper, which is fabricated on a thin, flexible substrate that can flex, bend, fold, twist, or curl like a conventional planar light source while maintaining its characteristics.

In a state in which the planar light source is not bent (for example, a state having an infinite radius of curvature, hereinafter referred to as a first state), the planar light source is flat. In a state where the surface light source is bent by an external force in the first state (for example, a state having a finite radius of curvature, hereinafter referred to as a second state), at least a part of the surface light source may be curved or curved. The surface light source may be switched from the first state to the second state, or may be switched from the second state to the first state.

The pixel of the surface light source may be implemented by a semiconductor light emitting device. In the present invention, a light emitting diode (LED) is exemplified as one type of semiconductor light emitting device for converting a current into light. The light emitting diode is formed in a small size, so that it can serve as a pixel even in the second state.

The plurality of planar light sources are arranged to bend or twist to form a three-dimensional structure, minimizing mutual interference. For example, the first surface light source and the second surface light source may be arranged to cross each other at one point, and at one point, a portion of the second surface light source may be covered by the first surface light source.

Each of the planar light sources may be formed as a strip line having a predetermined width, that is, a strip line. Each surface light source may have different widths and lengths.

As another example, when a plurality of surface light sources are sequentially turned on, a start effect may be generated in which the flame gradually rises.

Hereinafter, a vehicle lamp 800 implemented using the surface light source will be described in detail with reference to the drawings.

The vehicle lamp 800 may include a communication unit 810, a surface light source 830, a driving unit 850, and a control unit 880. It should be noted that the components shown in Fig. 9 are not essential for implementing the on-vehicle lamp 800, so that the on-vehicle lamp 800 described in this specification includes more or fewer components than the components listed above Lt; / RTI >

The communication unit 810 can receive information related to driving of the vehicle from various components provided in the vehicle. All information received through the communication lamp 810 by the vehicle lamp 800 is referred to as " vehicle running information ".

The vehicle running information may include vehicle information and peripheral information of the vehicle.

The vehicle information means information about the vehicle itself. The vehicle information includes, for example, the vehicle speed, the running direction, the acceleration, the angular speed, the position (GPS), the weight, the number of passengers on the vehicle, the brake operation, the braking force of the vehicle, the maximum braking force of the vehicle, (Automatic parking mode, automatic parking mode, manual parking mode), whether or not the user is boarding in the vehicle, and whether the user is in the vehicle And the like.

The peripheral information of the vehicle means information relating to other objects located within a predetermined range around the vehicle and information related to the outside of the vehicle. For example, the state of the road surface on which the vehicle is running (frictional force), the weather, the distance from the front (or rear) vehicle, the relative speed of the front (or rear) vehicle, Information related to an object existing in a reference area (a predetermined area) on the basis of the vehicle, whether the object enters / leaves the predetermined area, whether a user exists around the vehicle, and information related to the user Whether the user is an authorized user, etc.).

The planar light source 830 has one surface adapted to emit light. A supporting portion is connected to the other surface of the surface light source 830. The surface light source 830 may be fixed or supported on the frame of the vehicle lamp 800 by the supporting portion. The supporting portion and the frame may be integrally formed by injection molding at a low temperature sintering.

The support may be made of graphite made by low-temperature sintering. The graphite produced by the low temperature sintering is excellent in thermal conductivity and has an advantage that the injection shape can be freely formed. It is not only 50% lighter than aluminum, but also cost-effective in mass production.

The physical properties of the graphite are such that the metal content is added based on 100% of the carbon content so that the content of the above-mentioned catalyst is less than 90% to 100%. In other words, the support may be composed of graphite having a propene content of from 90% to less than 100%.

The support unit may serve as a heat sink for the surface light source 830 by transmitting the heat generated by the surface light source 830 as a frame.

Further, the support may be subjected to a surface treatment for suppressing the fine powder of graphite and for enhancing mechanical properties.

The surface light source 830 includes a plurality of surface light sources disposed at different positions. For example, the planar light source 830 may include a first planar light source, and a second planar light source that intersects the first planar light source at at least one point.

A plurality of planar light sources disposed at different positions can be formed into a three-dimensional shape different from the conventional lamp. The plurality of surface light sources may have different shapes so that the shape becomes more stereoscopic.

The driving unit 850 is connected to the other surface of the surface light source 830 and applies an external force to the surface light source 830. The driving unit 850 is driven under the control of the control unit 880 and generates an external force for deforming the surface light source 830.

The control unit 880 controls the overall operation of the vehicle lamp 800. The control unit 880 may process or process signals, data, information, and the like input or output through the components described above or may drive an application program stored in a memory (not shown) to provide or process appropriate information or functions to the user .

In addition, the controller 880 may control at least some of the components included in the on-vehicle lamp 800 to drive an application program stored in the memory. Further, the controller 880 may operate at least two of the components included in the vehicle lamp 800 in combination with each other for driving the application program.

For example, when the brake of the vehicle 100 is operated, the controller 880 controls the surface light source 830 to emit light at a predetermined brightness.

In another example, the controller 880 may control the driving unit 850 to generate a predetermined external force based on a signal (or vehicle running information) received from the vehicle.

Hereinafter, the organic operation of the planar light source 830 and the driving unit 850 will be described in detail with reference to the accompanying drawings.

FIG. 10 is a conceptual view for explaining the vehicle lamp of FIG. 9 more specifically, and FIG. 11 is an exploded perspective view for explaining a coupling relation of a plurality of surface light sources.

Referring to FIG. 10, the vehicle lamp 800 may include a plurality of surface light sources including a first surface light source 822 and a second surface light source 824. For convenience of explanation, the first and second surface light sources 822 and 824 are used to illustrate the present invention, but the present invention is not limited thereto, and more surface light sources may be included.

Each planar light source is connected to a corresponding support and can be fixed or supported on the frame 870 by a support. Further, each of the surface light sources has a unique shape due to twist, wrinkle, or bending, and the shape thereof is retained by the support.

On the other hand, the first surface light source 822 and the second surface light source 824 may be configured to intersect at at least one point. The intersection is to make a three-dimensional structure by the surface light sources, and can be done in a manner that does not come into contact with each other or in a manner of mutual contact.

The first surface light source 822 has a groove S and the second surface light source 824 is inserted into the groove S to be in contact with the first surface light source 822, .

When an external force is applied to any one of the first and second surface light sources 822 and 824, an external force is applied to the other surface light source through intersection points of the first and second surface light sources 822 and 824, The light sources 822 and 824 are simultaneously deformed.

For example, when the second surface light source 824 is moved in the Z axis direction by an external force applied by the driving unit, the first surface light source 822 is also deformed or moved by the external force applied to the second surface light source 824 Can be achieved. The deformation generated in the first surface light source 822 may vary depending on the characteristics of the external force applied to the second surface light source 824 and the position of the intersection point.

Embodiments in which an external force is applied to the surface light source 830 by the driving unit 850 will be described with reference to the drawings.

12A, 12B, 13A and 13B are illustrations for explaining the operation of the driving unit.

The controller 880 may control the surface light source 830 such that at least one of the hue, brightness, and saturation of the light generated by the surface light source 830 is changed according to predetermined conditions. Further, the controller 880 may control the driving unit 850 so that the external force applied to the surface light source 830 varies according to the predetermined condition.

Here, the predetermined condition may be a condition related to the vehicle running information. At least one of the degree to which the vehicle 100 is braked by the operation of the brake, the acceleration of the vehicle 100, and the possibility of collision generated from the other vehicle located behind the vehicle 100 may be related to the predetermined condition .

For example, when the acceleration due to braking is within the first range, a first external force may be generated in the driving unit 850 while the first light is generated in the surface light source 830. Alternatively, when the acceleration due to the braking is within the second range, the second light may be generated in the planar light source 830, and a second external force may be generated in the driving unit 850. The first and second lights indicate that at least one of hue, brightness, and saturation is different.

For example, if the possibility of collision is within the first possibility range, a third external force may be generated in the driving unit 850, and a fourth external force may be generated in the second possibility range. As the possibility of collision increases, the driving unit can be controlled so that a relatively large deformation occurs in the surface light source. Since the planar light source operates as a braking lamp, the driver of the other vehicle is more likely to collide as the deformation of the planar light source increases.

Meanwhile, the second surface light source 824 may be connected to at least one support portion 892 and 894. The at least one supporting portion may include a driving unit configured to apply an external force to the second surface light source 824, or may be a driving unit itself.

For example, the driving unit may apply an external force to the second surface light source 824 in one direction. Since the second surface light source 824 has the shape of a strip line, when an external force is applied at one point, the second surface light source 824 is deformed based on a fixed other point. In other words, deformation occurs in the surface light source due to the vector between the fixed point and the point at which the external force is applied.

The memory may store predetermined conditions, positions of supporting points corresponding to the preset conditions, and characteristics of external forces to be applied.

If any one of the predetermined conditions is satisfied, the controller 880 controls the driving unit 850 to apply a predetermined external force to the surface light source 830. Thereby, the surface light source 830 is deformed corresponding to any one of the above conditions.

A plurality of states may be preset for the second surface light source 824. The control unit 880 controls the drivers 892-896 so that the condition is satisfied if any one of the predetermined conditions is satisfied.

For example, as shown in FIG. 12A, the driving unit may be configured to apply an external force in one direction. In other words, the driving unit can be made so that one point of the surface light source connected to the driving unit is pushed or pulled in one direction. In this case, the planar light source can be deformed into a planar state in which it moves in one direction, wrinkles, or wrinkles.

As another example, as shown in FIG. 12B, the driving unit may be configured so that one point of the surface light source connected to the driving unit rotates. In this case, the surface light source may be twisted like a pretzel, or the twisted part may be deformed into a flat surface.

14A and 14B are conceptual diagrams for explaining a film disposed on a surface light source.

Since the planar light source follows the Lambertian emission pattern, it has a dependence of cosine function. 14, since the planar light source 822 according to the present invention includes the first and second portions 822a and 822b that emit light in different directions due to warpage, The light efficiency of the light becomes poor. This may cause a problem that the light quantity required by the regulations can not be satisfied.

In order to solve this problem, the surface light source 822 of the automotive lamp 800 according to the present invention may further include a film 1410 disposed on one surface of the surface light source 822 that is configured to emit light.

The film 1410 is configured such that different portions of the bent or twisted surface light source 822 emit light toward a predetermined range. In other words, the film 1410 is made to compress light in order to secure the light quantity required by the regulations.

The film 1410 may be disposed on at least a part of the surface light source 822. [ Specifically, the surface light source 822 may be divided into a first portion 822a facing a predetermined direction with respect to the Z-axis direction and a second portion 822b facing a direction other than the predetermined range, The film 1410 may be disposed on the second portion 822b.

The film 1410 is adapted to change the path of light emitted from the second portion 822b of the surface light source 822. [ For example, the film may be formed of a plurality of thin film layers having a predetermined refractive index. In another example, the light emitting device may include a plurality of protrusions having a predetermined shape so as to form a predetermined light distribution pattern, and may be formed of an optical layer made of a light-transmitting material.

Light emitted from the second portion 822b of the surface light source 822 passes through the film 1410 and is directed to a predetermined range with respect to the Z axis direction. Thereby, the amount of light required by the regulation can also be emitted through the bent surface light source to the predetermined range.

15A and 15B are conceptual diagrams illustrating a lamp for a vehicle that classifies one surface light source into a plurality of portions and controls the plurality of portions in different ways.

Sectional views of the first and second surface light sources 822 and 824 viewed in the X-axis direction.

One surface of each surface light source may be classified into a plurality of portions. In one example, the surface light source may be classified into a plurality of portions based on at least one of twisting, wrinkling, a direction in which a surface is directed, a distance from a predetermined reference line, and an intersection point of the first and second surface light sources.

For example, it may be classified as a flat portion that is less than or equal to the reference curvature, or a curved portion that has a curvature larger than the reference curvature. Or a front portion facing a predetermined range with respect to the Z-axis direction, and a side portion facing the predetermined range. Or a portion outside the reference line based on the preset reference line, and a portion inside the reference line. Alternatively, it can be classified into an intersection point outer portion and an intersection point inner portion with respect to an intersection point.

Such a classification may vary depending on the external force applied to the surface light source. This is because deformation occurs in the surface light source due to external force.

The control unit controls the surface light source so that at least one of the hue, brightness, and saturation of each of the portions is different. For example, referring to FIG. 15A, the baseline outer portion HL may be controlled to have a first brightness, and the baseline inner portion LL may be controlled to have a second brightness. Thereafter, when deformation occurs in the planar light source, the reference line outside portion HL and the reference line inside portion LL may be different as shown in FIG. 15B.

Since the plurality of portions are controlled differently, a more stereoscopic visual effect can be generated.
